Talk:Free hands input device

More Switch Ideas

I'm not really an electronics person, but could you use those little hall effect sensors mounted on the back on of each of your fingers in addition to a weak magnet mounted on the back of thumb to detect when a user brings their thumb and fingers together to signify input?
The input system I'm thinking about (and trying to learn the gestures for without an actual input device) would support a maximum of ~49 different inputs.
7 gestures for the right hand (thumb + fingers 1, 2, 3, 4, 1&2, 2&3, or 3&4) * 4 for the left (thumbs + fingers 1, 2, 3, or 4) = 28 inputs (English alphabet + space and period).

Including (adjacent) two finger gestures on the left hand would give a total of 49 combinations. You could also do three and four finger gestures, or use non-adjacent fingers, but these are harder to do and take more time.
I have a little Python script which translates strings into lists of finger positions (it isn't in alphabetical order as I thought it made sense to put the most frequently used letters on the easiest gestures).
